Re: Sharp Aquos LC-52D64U - Flashing Power



No, looks pretty white to me. I paused a blueray on a white screen (one of the attachments, not a perfect white screen, has a fade out to a skull or something). As far as the lines running up and down the screen, looks like tab bond issue to me. Was going to investigate that further if I had to take the screen completely apart (which I dread doing).

If I unplugged connector LA1 (Which goes to Inverter 1), I would show 60V on the power supply, so I replaced two of the four inverters (Inverters 1 (RUNTKA327WJZZ) and (Inverter 3 RUNKA329WJZZ) and was able to power up and get picture/sound,...
